Antero-lateral border cut into 9 close-set teeth of which the last is three times as long as any of the others. The posterior border is slightly curved and meets the postero-lateral borders at a well-marked angle, which is slightly turned up. Chelipeds in the adult male about 2ΒΌ times the length of the carapace. Arm with 3 spines on the anterior border and 1 at he far end of the outer border. Hand costate, armed with 2 spines. First 3 pair of legs slender, the first pair hardly shorter than the chelipeds.
